CompTIA Network+ (N10-009) — Question 190

A network engineer is testing a website to ensure it is compatible with IPv6. After attempting to ping the website by its IPv6 address, the engineer determines that the DNS has not been set up properly. Which of the following should the network engineer complete to resolve this issue?

Answer options

• A. Enable a PTR record.
• B. Update the existing TXT record.
• C. Add a new AAA record.
• D. Configure a secondary NS record.

Correct answer: C

Explanation

The correct answer is C, as adding a new AAAA record is essential for mapping an IPv6 address to the domain name. The other options do not address the need for a proper IPv6 record; enabling a PTR record is for reverse lookups, updating a TXT record does not help with address resolution, and configuring a secondary NS record is unrelated to the immediate DNS resolution issue.
